The search is centered on three buildings along Nutwood Avenue on the southeast edge of the campus, said Chris Bugbee, the school's director of public relations. Students were alerted via text message to shelter in place.

Occupants of Mihaylo Hall at the College of Business were evacuated.

"We saw all these cops coming through with - I think they were like AKs or something. They were pretty big guns. And they eventually told us we had to leave the campus," student Nate Chu told KABC-TV.

At least five suspects fled the scene of the robbery Wednesday in Moreno Valley and were stopped in Fullerton, Anaheim Police Sgt. Bob Dunn told KCAL-TV.

One person was detained and four others ran off.

One suspect carjacked a silver sedan and led police on a high speed chase along busy freeways and through residential streets before surrendering to more than a dozen officers some 60 miles away in Los Angeles.
